The Nexus 6P is not an easy phone to repair, according to iFixit. The site gave the device a score of 2 out of 10 for repairability after tearing it apart and seeing what’s inside. Hint: it’s a lot of glue.
To remove the screws holding the metal body together you have to remove pieces that are glued on, including the camera lens cover. The display is also held on by glue and is extremely hard to replace. Apparently replacing it without shattering it is a difficult task, and that’s the most common repair.
While it’s a shame that repairing this device is so difficult, most people don’t opt to repair their devices anyway. Make sure you get the Nexus Protect plan and keep your phone safe!
